This is a sporty windbreaker purchased from β beta, a Five Fox store. The vibrant blue color makes a big impact. There's a hood tucked into the zipper at the neck, so you can quickly pull it out to shield yourself from the rain, making it perfect for travel and leisure! It's also recommended for protection against air conditioning in the summer! (It is not waterproof. It's thin, so it's probably not suitable for heavy rain. 100% nylon) There are air vents under the arms to prevent stuffiness! The size is 42, which is about a size M!
